Query-Key normalization (QKNorm) [32] normalizes query and key vectors to have unit L2 norm. In nGPT, many vectors are normalized to have unit L2 norm: [33] hidden state vectors, input and output embedding vectors, weight matrix columns, and query and key vectors.
Feature scaling is a method used to normalize the range of independent variables or features of data. In data processing, it is also known as data normalization and is generally performed during the data preprocessing step.
The softmax function, also known as softargmax [1]: 184 or normalized exponential function, [2]: 198 converts a vector of K real numbers into a probability distribution of K possible outcomes. It is a generalization of the logistic function to multiple dimensions, and is used in multinomial logistic regression .
Thus, if and are real matrices, their normalized cross-correlation equals the cosine of the angle between the unit vectors and , being thus if and only if equals multiplied by a positive scalar. Normalized correlation is one of the methods used for template matching , a process used for finding instances of a pattern or object within an image.
If and are two left-singular vectors which both correspond to the singular value σ, then any normalized linear combination of the two vectors is also a left-singular vector corresponding to the singular value σ. The similar statement is true for right-singular vectors.
The basic eight-point algorithm is here described for the case of estimating the essential matrix .It consists of three steps. First, it formulates a homogeneous linear equation, where the solution is directly related to , and then solves the equation, taking into account that it may not have an exact solution.
The random walk normalized Laplacian can also be called the left normalized Laplacian := + since the normalization is performed by multiplying the Laplacian by the normalization matrix + on the left. It has each row summing to zero since P = D + A {\displaystyle P=D^{+}A} is right stochastic , assuming all the weights are non-negative.
In another usage in statistics, normalization refers to the creation of shifted and scaled versions of statistics, where the intention is that these normalized values allow the comparison of corresponding normalized values for different datasets in a way that eliminates the effects of certain gross influences, as in an anomaly time series.
